Description

Cooling apparatus and method of control the same}

The present invention relates to a cooling device and a method of controlling the same, and more specifically, to a cooling device and a method of controlling the same that can improve energy efficiency and cooling efficiency.

A water purifier is a general term for any device that receives raw water, processes it to the state desired by the user, and then provides it to the user. A water purifier can filter raw water using various types of filters and provide it to the user. As an example, a water purifier may filter raw water to make it suitable for drinking and provide it to the user.

As living standards improve and users' needs diversify, water purifiers that can perform additional functions beyond providing purified water by filtering raw water have recently become popular. For example, recently, water purifiers that can provide hot water, cold water, and even ice to users have been commercially available and are selling very well.

Typically, a water purifier for dispensing cold water is equipped with a tank for receiving purified water and a structure for cooling the purified water stored in the tank. The above type of water purifier may be referred to as a tank-type water purifier. Tank-type water purifiers are widely used because they can dispense a large volume of cold water at once.

In the case of a configuration for cooling purified water contained in a tank, it is generally operated by receiving electric power. In particular, in order to simultaneously achieve the miniaturization of the water purifier and the cooling effect of the purified water, the above configuration is often equipped with a thermoelectric element. As is known, thermoelectric elements are configured to perform cooling using the Peltier effect.

In the case of water purifiers currently on the market, a thermoelectric element is coupled to the tank itself to accommodate purified water, thereby cooling the purified water. Therefore, when the thermoelectric element and the fan connected thereto stop, the temperature of the cold water stored in the tank increases, and the thermoelectric element and the fan connected thereto are configured to operate continuously.

This is a problem during late-night hours when users are less likely to dispense purified or cold water. That is, since the thermoelectric element and fan must continue to operate even while purified water or cold water is not discharged, power efficiency is reduced, and the user's sleep effect is likely to be reduced due to noise caused by the operation of the fan.

Korean Patent Publication No. 10-2009-0019614 discloses a water purifier having a dual cold water tank. Specifically, including a sub cold water tank that communicates with the purified water tank and stores cold water, and a main cold water tank that receives purified water from the sub cold water tank and cools it, if the temperature difference between the water stored in the sub cold water tank and the main cold water tank is greater than the standard value, the main cold water tank Disclosed is a water purifier configured to supply water from a tank to a sub cold water tank.

However, the prior literature only provides a method for maintaining cold water at a desired temperature based on the temperature difference between the water stored in the main cold water tank and the sub cold water tank. In other words, the prior literature does not provide a method for maintaining the temperature of the already generated cold water, although it is possible to stop the operation of the cooling device when the frequency of water discharge is low.

Korean Patent Publication No. 10-2021-0131883 discloses a cooling device and a cooling system for a water purifier using the same. Specifically, a cooling device with a structure that prevents deterioration of the cooling performance of the thermoelectric element and increases the flow rate of coolant by arranging a plurality of cold water tanks facing each other with a cold sink connected to the thermoelectric element in between, and a water purifier using the same Start the cooling system.

However, the prior literature does not provide a method for increasing power efficiency by varying the operating state of the thermoelectric element. In addition, the above prior literature also fails to provide a method for maintaining the temperature of the already generated cold water, although it is possible to stop the operation of the thermoelectric element when the frequency of water extraction is low.

According to the above configuration, the energy efficiency of the cooling device and its control method according to an embodiment of the present invention can be improved.

The cooling device is provided with a main tank and a sub tank in communication with the main tank. The main tank is fluidly connected to the outside of the cooling device to receive and store the filtered fluid. Additionally, the fluid stored in the main tank may leak out of the water purifier through the water outlet module.

The sub tank receives the fluid flowing into the main tank. The sub tank is coupled with a heat exchange unit, so that the fluid flowing into the sub tank can be cooled by the heat exchange unit. The cooled fluid is returned to the main tank and stored.

In one embodiment, the sub tank may be formed to be smaller than the main tank. That is, compared to the case where the heat exchanger is directly coupled to the main tank, the amount of power required for the heat exchanger to cool the fluid flowing into the sub tank can be reduced.

Additionally, the cooling device is equipped with a control unit that controls the configuration of the heat exchange unit and sub tank. The control unit calculates control information for controlling the configuration of the heat exchange unit and the sub tank using temperature information of the fluid contained in the main tank or water discharge information about whether fluid is discharged from the main tank. The control unit may control the heat exchange unit and sub tank corresponding to the calculated control information.

In one embodiment, when the temperature of the fluid stored inside the main tank falls within a preset reference temperature range, the control unit may stop the operation of the heat exchange unit and the sub tank. Additionally, if fluid does not flow out of the main tank to the outside of the cooling device for a preset reference time, the control unit may stop the operation of the heat exchange unit and the sub tank.

Accordingly, when the temperature of the fluid stored in the main tank is sufficiently low or when the fluid stored in the main tank does not continuously flow out, the operation of the heat exchange unit or sub tank may be automatically stopped. Accordingly, the amount of power required to operate the cooling device can be reduced, thereby improving energy efficiency.

Additionally, according to the above configuration, the cooling device and its control method according to an embodiment of the present invention can reduce noise generated when not used for a long period of time.

As described above, the controller may control the heat exchange unit or sub tank to stop operation when fluid does not flow out of the main tank to the outside of the cooling device for a predetermined period of time.

Accordingly, when not used for a long time, the operation of the fan member, which is the main noise source, is stopped, and the noise generated from the cooling device can be reduced.

In addition, according to the above configuration, the cooling device and its control method according to an embodiment of the present invention can maintain the temperature of the fluid even when not used for a long period of time.

The heat exchange unit is combined with the sub tank. The cooled fluid is stored in the main tank spaced apart from the heat exchanger. The main tank body, which forms the exterior of the main tank, is made of an insulating material, so that heat exchange between the fluid stored in the main tank and the outside can be minimized.

Additionally, even if the operation of the heat exchange unit is stopped, the fluid stored inside the main tank does not directly exchange heat with the heat exchange unit. Accordingly, the temperature of the fluid stored inside the main tank can be maintained in a cool state.

Meanwhile, the sub tank and the main tank are fluidly connected by a sub communication part and a tank flow path part. In one embodiment, the sub-communication part and the tank passage part may be provided with a check valve that opens or closes by a pressure difference. When the operation of the pump member is stopped, the check valve closes the sub communication part and the tank passage part to block communication between the sub tank and the main tank. The pump member may be operated corresponding to the operation of the heat exchanger.

Therefore, when the heat exchanger stops operating, the pump member also stops operating, thereby blocking communication between the main tank and the sub tank. Accordingly, the fluid stored in the main tank does not mix with the fluid stored in the sub tank, and its temperature can be maintained in a cool state.

Additionally, according to the above configuration, the cooling device and its control method according to an embodiment of the present invention can improve fluid cooling efficiency.

Inside the main tank, a main partition member is provided that forms a flow path through which fluid flows. The main partition member divides the internal space of the main tank into a plurality of spaces that communicate with each other. Fluid may be stored in a plurality of partitioned spaces, flowing in a zigzag shape along the main partition member.

As described above, the cooling process of the fluid is performed in a sub tank directly coupled to the heat exchanger. Accordingly, since cooled fluid flows into the main tank, heat exchange efficiency by convection within the main tank can be improved.

In one embodiment, the fluid cooled in the sub tank may flow into the main tank through the upper side of the main tank. Additionally, fluid in the main tank may leak into the sub tank through the lower side of the main tank.

Accordingly, the temperature gradient of the fluid inside the main tank can be minimized. As a result, the cooling efficiency of the fluid can be improved.

In addition, according to the above configuration, the cooling device and its control method according to an embodiment of the present invention can improve processing convenience and reduce manufacturing costs.

As described above, the heat exchanger is directly coupled to the sub tank. Therefore, the main tank can be made of a material that can block any heat exchange between the fluid stored inside and the outside. That is, expensive insulating materials are used only in the sub-tank components that are in direct contact with the heat exchanger, and other components of the main tank and sub-tanks can be made of insulating materials to achieve a sufficient cooling effect.

In the case of insulating materials, the manufacturing cost is low and the manufacturing process required is simple compared to highly thermally conductive materials such as synthetic resin or Styrofoam. Accordingly, the convenience of each configuration of the cooling device and processing of the cooling device can be improved and the manufacturing cost can be reduced.

The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description or claims of the present invention.

Referring to FIG. 1, the communication relationship of each component of the water purifier 1 including the cooling device 10 according to an embodiment of the present invention is disclosed as a block diagram.

The water purifier 1 is fluidly connected to the outside and can receive unfiltered fluid, for example, raw water. The water purifier 1 may include a filtration module 20 for filtering unfiltered fluid. The filtration module 20 may be provided in any form, such as a filter capable of filtering raw water. The fluid flowing into the water purifier 1 may be filtered while passing through the filtration module 20.

In addition, the water purifier 1 may include any means for heating or cooling the filtered fluid (i.e., a cooling device 10 to be described later). The filtered fluid is discharged to the outside after being adjusted to a temperature desired by the user. and can be provided to the user.

To this end, the water purifier 1 is fluidly connected to the outside and may include any means for heating or cooling the filtered fluid (i.e., cooling device 10).

In the illustrated embodiment, the water purifier 1 includes a cooling device 10, a filtration module 20, and a water outlet module 30.

The cooling device 10 is configured to cool the fluid filtered by the filtration module 20 . The cooling device 10 may exchange heat with the filtered fluid to cool the fluid. The cooled fluid may flow out to the outside and be provided to the user.

The cooling device 10 may be provided in any form for cooling the filtered fluid. The cooling device 10 can be connected to an external power source (not shown) to receive power required for operation. Although not shown, the water purifier 1 may further include an input unit (not shown) that receives a control signal for operating the cooling device 10.

A detailed description of each configuration of the cooling device 10 and the process by which fluid flows in, cools, and then flows out accordingly will be described later.

The cooling device 10 is fluidly connected to the outside of the water purifier 1 through the filtration module 20. Additionally, the cooling device 10 is fluidly connected to the outside of the water purifier 1 through the water outlet module 30.

The filtration module 20 receives unfiltered fluid and filters it to suit its purpose. The filtration module 20 is fluidly connected to the outside of the water purifier 1 and the cooling device 10. The fluid filtered while passing through the filtration module 20 may be delivered to the cooling device 10.

The water outlet module 30 is fluidically connected to the outside to transfer the fluid that has passed through the cooling device 10 to the outside. The water outlet module 30 fluidly connects the cooling device 10 and the outside.

The water outlet module 30 may be provided in any form that can fluidly connect the cooling device 10 to the outside of the water purifier 1. In one embodiment, the water outlet module 30 may be provided in the form of a pipe. In the above embodiment, the water outlet module 30 is provided with valves that operate in various forms, so that the outflow of the cooled fluid can be controlled.

2 to 3, a cooling device 10 according to an embodiment of the present invention is shown.

The cooling device 10 is accommodated inside the water purifier 1 and is fluidly connected to the filtration module 20 and the water discharge module 30, respectively. The cooling device 10 can cool the fluid that flows in after being filtered while passing through the filtration module 20. The cooled fluid may flow out along the water outlet module 30.

The cooling device 10 according to an embodiment of the present invention may include a plurality of members that store fluid. That is, the cooling device 10 according to an embodiment of the present invention may be formed in a tank type. One of the plurality of members is fluidly connected to the filtration module 20 and the water discharge module 30. The filtered fluid may flow into any one of the above and may flow out through the water outlet module 30.

Additionally, another one of the plurality of members is fluidly connected to one of the plurality of members. The fluid that has passed through the filtration module 20 passes through one of the above and flows into the other.

A configuration for cooling the inflow fluid is coupled to the other one. That is, the cooling process of the fluid is carried out in the other configuration.

At this time, the other one may be formed to have a smaller size than the other one. Accordingly, the power required to cool the introduced fluid can be reduced. In addition, since the cooled fluid is transferred to and stored in one of the above, the temperature of the cooled fluid can be maintained even if the fluid cooling process is not performed.

In the embodiment shown in FIGS. 2 and 3, the cooling device 10 includes a main tank 100, a coupling frame 200, a heat exchanger 300, and a sub tank 400. Additionally, referring to FIG. 12 , the cooling device 10 according to the illustrated embodiment further includes a control unit 500.

The main tank 100 forms part of the external shape of the cooling device 10. The main tank 100 is a part where the cooling device 10 is fluidly connected to other components of the water purifier 1, that is, the filtration module 20 and the water discharge module 30.

The fluid filtered while passing through the filtration module 20 may flow into the main tank 100. Additionally, fluid flowing in the main tank 100 may be discharged to the outside through the water outlet module 30. For this purpose, a space communicating with the outside is formed inside the main tank 100.

The main tank 100 forms one side of the cooling device 10. In the illustrated embodiment, main tank 100 forms the rear side of cooling device 10.

The main tank 100 is coupled to the coupling frame 200. The main tank 100 is coupled to the sub tank 400 through a coupling frame 200. In the illustrated embodiment, the sub tank 400, the coupling frame 200, and the main tank 100 are arranged in order from the front side to the rear side.

The main tank 100 is combined with the sub tank 400. The main tank 100 may be fluidly connected to the sub tank 400 through a sub communication part 450 and a tank passage part 460 provided in the sub tank 400.

4 to 5, the main tank 100 includes a main tank body 110, a main tank space 120, a main communication part 130, a main partition member 140, and a main temperature sensor ( 150).

The main tank body 110 forms the external shape of the main tank 100. A space (that is, a main tank space 120 to be described later) is formed inside the main tank body 110. The space is fluidly connected to the outside so that fluid can flow in or out.

The main tank body 110 is coupled to the coupling frame 200. The space formed inside the main tank body 110 may be closed by the coupling frame 200. In the illustrated embodiment, the front side of the main tank body 110 is coupled with the coupling frame 200.

The main tank body 110 may be formed to be larger than the sub tank body 410 provided in the sub tank 400. In other words, the main tank body 110 has a larger volume than the sub-tank space 420 formed inside the sub-tank body 410 (i.e., the main tank space 120). It can be formed to have

Accordingly, the amount of fluid remaining in the main tank 100 increases compared to the amount of fluid cooled in the sub tank 400. As a result, the fluid that has passed through the filtration module 20 may be continuously cooled and then flow into the main tank 100.

The main tank body 110 has a main tank space 120 formed therein, and may be of any shape capable of being combined with the coupling frame 200. In the illustrated embodiment, the main tank body 110 has a polygonal column shape that has a width in the left and right directions, a height in the up and down directions, and a depth in the front and rear directions.

The main tank body 110 may be made of an insulating or heat-retaining material. This is to prevent a situation where the fluid stored in the main tank space 120 is heated or cooled by heat exchange with the outside. In one embodiment, the main tank body 110 may be made of synthetic resin (resin) material. In another embodiment, the main tank body 110 may be surrounded by an insulating material such as foamed Styrofoam.

That is, in the main tank body 110 according to an embodiment of the present invention, the fluid contained in the main tank space 120 is not directly cooled. Therefore, even if the main tank body 110 is not made of a relatively expensive material with a high heat transfer rate, the fluid can be cooled and provided to the outside. Accordingly, the manufacturing cost of the main tank 100 and the cooling device 10 can be reduced, and the manufacturing process can be simplified.

The main tank space 120 is a space formed inside the main tank body 110. The main tank space 120 receives and stores filtered or cooled fluid.

The main tank space 120 is fluidly connected to the outside. The main tank space 120 is fluidly connected to the filtration module 20 and the water discharge module 30, respectively.

Through the space, a plurality of partitioned small spaces can be communicated with each other.

Additionally, the front-to-back width of the main partition member 140 may be equal to the front-to-back depth of the main tank space 120.
